Patent CA-2144021-A1 (CA)
Inventor: LUSS V GEROLD
IPC: A01N37/44
Filed: 1995-03-06
Abstract: The invention provides environmentally acceptable sanitizing and microbicidal compositions that are safe to humans and/or animals,  which may be used to sanitize surfaces and equipment used to prepare, process or manufacture food, pharmaceuticals or other preparations which should receive protection fromcontact with microbial contamination during manufacture. These compositions substantially reduce or eliminate residual microbial contamination which may reside on an equipment surface or in ancillary equipment such as valves, pipes, filters, and the like. The present concentrated compositions comprise a water soluble short chain organic acid component with a carbon chain length in the range C1--C4 which provides an acid pH value in a range of about 1.5 - 4.0 upon dilution with an excess of water, an intermediate chain length fatty acid component with carbon chain length in the range C6--C16, an anti-oxidant phenolic compound component, a solubilizercomponent chosen from hydrotropes and surfactants, present in an effective amount for solubilizing the intermediate chain length fatty acid component and the phenolic component when the microbicidal concentrate is in a diluted form with water, andoptional components which may be added to control or enhance foam, and aid in control of water hardness, viscosity and stability.
Patent CA-2144408-A1 (CA)
Title: Intrusion detection system
Inventor: HARMAN ROBERT K
IPC: G08B13/24
Filed: 1993-09-10
Abstract: In an intrusion detection system comprising an open transmission line (10), for example a "leaky cable", and a receiver un-it (12S, 12T, 145, .14T, 16) for processing a radio frequency signal received by the line to detect perturbations caused by an intrud-er (28), problems of nonlinear sensitivity due to line attenuation are resolved by combining perturbation signals (R S, R T) from both ends of the open transmission line. A processor unit (18) computes logarithmic values of the perturbation signals from the opposite ends of the line and combines them to detect presence of an intruder. The sum of the logarithmic values may be used to determine presence of the intruder and the difference between them may be used to determine the location of the in-truder relative to the end of the line. The processor may also use phase information from the two perturbation signals to fa-cilitate detection in the presence of multipath effects. Reference signals (LO, IF T, RF) and power may be transmitted be-tween receiver units (12S, 145, 12T, 14T, 16) by way of the open transmission line (10) itself. The system may employ several transmissions having different frequencies, in which case the processor (18) will sum perturbation signals for all trans-mission frequencies for each end of the line, combine the two sums, and compare the result with a predetermined threshold

Title: Dosing feeder for the breast box of a papermaking machine
Inventor: LEHLEITER KLAUS
IPC: D21F1/02
Filed: 1995-03-17
Abstract: The metering device (5) according to this invention, serves for the addition or the removal of fluids into or from the breast box  (1)  of a papermaking machine.   It includes a chamber (6)  for the reception of fluids, with the chamber including a number of metering openings  (9,  9')  that are connected with the suspension-carrying parts of the breast box via throttling devices (4).  Thereby, the fluid can be added or removed locally, in a metered manner, without requiring a confusing and expensive distribution via hoses or other such pipes, which, based or experience, when using a greater number of dosing points, leads to placement and operational problems.

Patent CA-2146291-A1 (CA)
Title: Jack-axe
Inventor: TORMA AUSTIN
IPC: B27L7/08
Filed: 1995-04-04
Abstract: A device for splitting wood for fuel comprises a body and attaching member and fastener.  The device is designed to be mounted on a manually operated mechanical jack; the precise descriptive, jack-axe, is used to differentiate the device from other known woodsplitting devices.  The body has two planar faces, the surfaces and profile boundaries of which describe a solid.  The surfaces converge toward each other to describe a narrow lower boundary or blade edge which creates an advantage for the body in its preferred operation of penetrating and splitting cut wood for fuel.  The attaching member is joined to the body and protrudes from an edge adjacent to the blade edge.  Thus, the device can be attached to the beam of a jack and its position adjusted in a sliding manner to accommodate the size of wood to be split; the blade edge pointing toward the lifting member of the jack.  Wood to be split is placed against the beam of the jack, between the lifting member and the device, with a grain splitting direction parallel to the beam.          Operating the jack handle causes the lifting member of the jack to push the wood into the body of the device thereby splitting the wood in a controlled deliberate effort.

Title: A prosthetic vascular graft
Inventor: CAMPBELL CAREY V
IPC: A61F2/06
Filed: 1993-12-10
Abstract: - A vascular graft in the form of a tube (11) or flat sheet of biocompatible material having an outer covering of deflectably secured material such as porous film, fibers (15), discrete pieces of material, or combinations thereof. Two different types of fibers may also be used. The vascular graft may be of tubular form for replacing or bypassing entire segments of veins or arteries or alternatively may be in the form of a flat sheet useful for repairing portions of the circumference of veins or arteries. The tube (ll) or flat sheet of biocompatible material and the outer covering of defectably secured material are preferably of porous poly-tetrafluoroethylene The inventive vascular graft is useful for dialysis access in that it offers a reduction in blood leakage when the vascular graft is punctured by a dialysis needle and the needle is subsequently removed. It is also useful for reducing suture hole bleeding resulting from holes created through the graft by penetration of the graft with a suture needle.

Inventor: CASTLE T KEVIN
IPC: B60T17/00
Filed: 1996-04-16
Abstract: A switching and purging mechanism is disclosed for controlling flow of gas within a twin tower gas drying system.  The drying system filters unpurified gas to supply purified gas to a pneumatic system with a purge percentage for purging moisture previously retained.  The mechanism includes a valve body, first and second pistons, and a control means.  The body defines first and second bores, first and second supply passages, first and second output ports, and first and second purge ports.  Through the control means, the first piston occupies a supply position while the second piston occupies a purge position and vice versa.          When the first piston occupies the supply position, unpurified gas flows from the first passage through the first bore through the first output port and communication between the first output port and the first purge port ceases.  When the first piston occupies the purge position, remoisturized gas flows from the first output port through the first bore through the first purge port and communication between the first passage and the first output port ceases.  When the second piston occupies the supply position, unpurified gas flows from the second passage through the second bore through the second output port and communication between the second output port and the second purge port ceases.        When the second piston occupies the purge position, remoisturized gas flows from the second output port through the second bore to the second purge port and communication between the second passage and the second output port ceases.
